Inflammatory pseudotumor in the urinary bladder

Inflammatory pseudotumor is a rare lesion in the urinary bladder, difficult to differentiate from bladder malignancies on clinical grounds only. We present a case report of the inflammatory pseudotumor of the bladder in a 26 year-old female, who sought medical advice due to non-specific discomfort in the perineal region and lower abdomen. On ultrasound scan and computed tomography a mass in the left pelvic cavity was identified, attached to the wall of the bladder, compressing the left ovary. The patient was treated surgically with partial cystectomy. A diagnosis of inflammatory pseudotumor was made on histologic assessment of the surgical specimen. Five years of follow-up has been relapse-free in this patient. Due to the relative rarity of inflammatory pseudotumor in the bladder, no diagnostic and treatment algorithm for this entity has been created to date.
